OF NORFOLK, VIRGINIAs ICE-CRUSQHER.'

SPECIFICATION forming part of Letters Patet No. 625,201, dated May 16,1899.

Application filed January 6, 1 899.

To all whom, t may concern.:

Be it known that I, RICHARD E. PRocToR, a citizen of the United States,residing at Durham, in the county of Durham and State of North Carolina,have invented new and useful v struction and combination of partshereinafter fully described and claimed.-

In the accompanying drawings, Figure lis a `perspective view of anVice-crusher constructed in accordance with my invention. Fig. 2 is adetail longitudinal section on the line .fr Fig. 3. Fig. 3 is a bottomplan view.

In the said drawings, the reference-numeral l designates a heavy woodenhandle of any suitable length and size, squared at the lower end and theupper end rounded, so as to be conveniently grasped by the ends. Fitting'on the lower end of this handle is a correspondingly-formed cap 2,provided with a setscrew 3, by which it is securely held in place.Formed integral with this cap is a circular bottom plate 4, theperiphery of which projects beyond the sides of the oap for a purposehereinafter described. This plate is formed with a number ofscrew-threaded holes 5, which coincide with a number of holes 6 in thehandle, which said last-mentioned holes extend some distance above theupper end of the cap. Engaging with these holes vare a correspondingnumber of screw -threaded prongs 7 formed intermediate the ends withangular collars S, with which a wrench or similar tool is adapted toengage in inserting and removing the same. The outer ends of theseprongs are tapered and beveled to a point, so as to be angular incross-section, the sides forming cutting edges, which materially assistin the operation of crushing the ice. I have shown iive of said prongs;but the num- Serial N0. 701,385. (N6 inodel.)

ber is notessential, and they are toV be made of the best temperedsteel, so as to withstand the rough usage to which they are to besubjected.

In use the handle is grasped by the two hands near the upper end andreciprocated up and down, the prongs striking the ice with considerableforce, so that it will be readily and quickly broken up 0r crushed intosmall lumps or pieces of a size suitable for the purpose intended. Ifany of the prongs should be broken, they can be readily removed byengaging a wrench with the angular collar and turning the same. Thesecollars also serve to brace the prongs against the circular bottom plateand prevent them from bending or twisting at such point.

The object of making the bottom plate circular is that the peripherywill proj ect beyond the sides of the cap, forming iianges which serveto engage a block of ice in order that it may be pulled toward theoperator to be broken by the prongs.

The invention is more especially designed for use in fish-packinghouses, restaurants, and ice-cream factories; but it is obvious that itcan be used in other places where large quantities of ice are requiredto be broken up or crushed.

The device should be quite heavy, so that its weight alone will besuflicient to crush the ice without any special eiort on the part of theoperator.

Having thus fully described my invention, what I claim is `1. As animproved article, an ice-crusher comprising the handle formed with aseries of holes in its lower end, the angular cap fitting on'the end ofsaid handle 'and formed with an integral bottom plate provided with aseries of screw-threaded holes coinciding with the holes in the handle,and the screwthreaded prongs engaging said holes having their outer endsformed into beveled points and the sides forming cutting edges and theintermediate collars on said prongs abutting against said bottom plateand made angular and adapted to be engaged by a wrench, substantially asdescribed.
